Figure 12: Removing a Power Supply
Setting the Input Mode Switch on a Three-Input 240-A Power Supply
NOTE: Do not set the input mode switch if the power supply is installed in the chassis.
If the power supply is already installed, you must remove it before setting the input
mode switch.
To set the input mode switch:
1. Using a screwdriver, loosen the captive screw holding the metal cover over the
input mode switch (see Figure 13 on page 22).
2. Rotate the metal cover away from the input mode switch to expose the switch.
3. Check the setting of the input mode switch. Use a flashlight, if necessary. In
3-INPUT mode, the switch is located all the way to the left.
4. Use a sharp, nonconductive object to slide the switch all the way to the left to
set the power supply to three-input mode.
CAUTION: Do not use a pencil, because fragments can break off and cause damage
to the power supply.
5. Rotate the metal cover over the input mode switch, and use a screwdriver to
tighten the captive screw.
Figure 13 on page 22 shows the input mode switch.
